This invention videa 'balanced valve"serving both as an inl'gt and exhaust valve\njith means for 'actuating the said valve in` timed relation to the reciprocation of the pistons.

A furtherI` .object of the invention is' to provide al piston .having two portsserving alternately as.

-a` valvejlc'ated androtating between'the f invention consists in the ports, said valve being'provlded with passages proportioned and positioned to comf municate with 'the ports, at proper. timed intervals to serve .l With .these and other objects in view the' construction, comhina-tion and arrangementof parts as will be hereinafter more fully described, illustrate'd in the accompanying drawings, and

'pointed out in" the claims hereunto a'ppended.

a partition l14' preferably.waterjacketedas indicated at Fig. 2. 4 The partition 14:

.is provided upon 1 its upper side with aqbe'ar'ing surface .15 for formed-'betweenthesald partition and 'the' upper part of the cylinder.

l The valve' 16 comprises .an outer shell proportioned .to rotate-in 'the bearing surraces lan'd. 17 and withiafeoncentricfinner tube 21" extending substantially the' entirev length of such valve.' At its niiddle'the outer -shell 20 is interrupted a`s' indicated .at

and communicates With'apassage 23 sup' plyingA explosive' mixture to the engine.' This interrupted space 22 extends entirely around the valve and is at' all times in com# munication' with the passage 23,` so thatthe space' b'etweenthe outer shell 201- and the. inner tube 21' is continuously' filled with `'the explosive mixture. Through the outer shell 21 ports 2 4 yare formed` positioned to' register at times with the passages 12 and 20 andthe inner tubev 21 is put in communlcation with the cylindery vl1 to receive a charge ofthe explosive mixture `from suchchamberfv The outer s hell'20 i's-'provided with two `of the ports 24 for each of thecyl; 'inders located at diametrical'points, so that two of the ports 24 are 'simultaneouslyiin' registry with the"ports 18'and19 by which` (arrangement thedischarge o 'f explosive mix-L'I l i ture from the chamber into the pistons 12 21 serves' as .an exhaust" The inner ytube 13 so that as the valve.- rotates' the chamber between the outer shell.

f For the purpose of lubricating ythe valve 16 a furrow 2 8 'is'forined throughout the entire lengtliofthe bearing surface 15 and at the middle -Where the bearing surface isl in terriiptedgis continued by a passage 29, through the filler bloclrO, which accommodates the inlet passage 23. Oil is supplied the compartment 3l-by any usual and ordinary forcing mechanism, suoli as a pump or the like, and rising in such compartment 31 passes through the entire length of 'the furrow 28 with its intervening passage 29, and is discharged'through the therefore. that as the valve 16 rotates it will be lubricated Jfrom said furrow 28 and will alternately discharge explosive. mixture from the inlet passage' into the passages 12 l and 13 and into the cylinder 11 upo-n .opposite sides ofl the valve 16 toaccurately bal ance such valve and -tliat the exhaust port-s as the valve rotates will also simultaneously register with the passages 12 and 13 to like- Wise balance the valve. l claim: 1.

8. The combination with ali internal-coinv bastion cylinder, having passages leading therefrom terminating in spaced ports, of a cylindrical valve mounted to rotate between the ports and embodying an inner exhaust chamber and an outer inlet chamber, a valve casing inclosing the valve and comprising two sections spaced apart, means includingan independent annular -inember having an inner annular channel disposed between saidy sections ,to supply an explosive mixture to the inlet chamber. said chamber having diametrically 4spaced ports positioned to/ at times register with the passages ofthe cylin e der and an exhaust conduit having diametrcallyy disposed ports positioned to at other times register with the passages `of the cylinder, the casing for the valve iiieluding a' partition wall between the spaced ports, one port of each chamber being simulH taneoiisly cut by said partition wall.

4. rhe combination with a iilnrality oft internal combustion chambers and i'iistoiisl reciprocating therein, of a cylindrical valve mounted to rotate across and in communication with the several cylinders, a casing for the valve-formed in sections spacedapart, a filler member located between said sections and formed with 'a channel admittinggas to the valve, a furrow foi-ined vin the casing along the under side of the valve, and means to pass a lubricant through the furrow, the ille'r member having a passageway for the lubricant. i,
